Wireless communication of channel state information using a single physical uplink channel

摘要

If a plurality of channel state information reports corresponding to different cells have collided (Yes in step S2408), a mobile station device 1 selects two channel state information reports in accordance with priorities of report types and cell indices of cells, and drops the other channel state information reports (step S2412). The mobile station device 1 transmits the selected two channel state information reports using a resource for PUCCH format 3, which is used in case of collision of a plurality of channel state information reports corresponding to different cells (step S2414).

1. A mobile station device that communicates with a base station device by using a plurality of cells, comprising:
measuring circuitry that calculates channel state information, and transmitting circuitry that:
(i) transmits, in a case that (a) simultaneous physical uplink control channel and physical uplink shared channel transmission is not configured, (b) a first physical uplink control channel resource is configured, and (c) there is one periodic channel state information report in a subframe where the physical uplink shared channel is not transmitted, the one periodic channel state information report on at least one of a plurality of second physical uplink control channel resources, one of the plurality of second physical uplink control channel resources being configured for each of the plurality of cells; and(ii) transmits, in a case that (a) the simultaneous physical uplink control channel and physical uplink shared channel transmission is not configured, (b) the first physical uplink control channel resource is configured, and (c) there are two periodic channel state information reports in the subframe where the physical uplink shared channel is not transmitted, one or two of the two periodic channel state information reports on the first physical uplink control channel resource, the first physical uplink control channel resource being used for transmission of a first physical uplink control channel format, the each of the plurality of second physical uplink control channel resources being used for transmission of a second physical uplink control channel format, and in a case that the simultaneous physical uplink control channel and physical uplink shared channel transmission is not configured, the transmitting circuitry transmits one or more of the periodic channel state information reports on the physical uplink shared channel in a subframe where the physical uplink shared channel is transmitted.
